Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transfer coating machines, and more particularly to a thinning device applied to a transfer coating machine. BACKGROUND

[0002] Lithium ion batteries have been widely used in the fields of electric vehicles and energy storage power stations in recent years due to their high energy density, high energy storage efficiency and long cycle life. Among them, the coating process is the most important link in the manufacturing process of lithium ion batteries. The transfer coating machine is used for coating. The transfer coating machine is mainly used to uniformly coat the slurry with good stability, suitable viscosity and good fluidity on the positive and negative current collectors. Due to the differences in the flowability of slurry with different viscosities and solid contents, the existence of surface tension of slurry, and the use of foam baffles and other reasons, the slurry often accumulates on both sides of the coating edge during the transfer coating process, resulting in a thickness of several microns to tens of microns at the edge of the coating compared to the normal area. This uneven thickness can cause the edge of the pole piece to be thick, and in severe cases, the pole piece can even be broken, which not only affects the neatness of the coating and winding, but also seriously affects the subsequent process.

[0003] In view of the above problems, a transfer coating machine coating thinning device is disclosed in the utility model patent with the authorization announcement number CN209549883U, which comprises a steel roller, a knife roller, a rubber roller and a foam baffle. The steel roller and the rubber roller are arranged in parallel on the same horizontal plane. The knife roller is arranged vertically above the steel roller. The foam baffle is supported on the steel roller in a left-right symmetrical manner. The coating thinning device further comprises a group of rubber belts, which are adhered to the knife roller in a left-right symmetrical manner. The distance between the inner side edge of each rubber belt and the inner side edge of each foam baffle is 2-4 mm. In this technical solution, a group of rubber belts are adhered to the knife roller, and the distance between the inner side edge of the rubber belt and the outer side edge of the baffle is accurately controlled, so that the coating amount of the edge of the continuous coating area can be accurately thinned, and the "edge explosion" phenomenon at the edge of the continuous coating area can be avoided. However, the thinning device needs to re-paste the rubber belt under different coating width or thickness requirements, which is not only time-consuming but also tedious. The repeated debugging process affects the production efficiency, and it is difficult to quickly adapt to different coating requirements. In addition, since the position of the rubber belt is fixed, it cannot be dynamically adjusted during the coating process, which limits its adaptability and flexibility under different coating conditions. Therefore, there is still a need for a thinning device that can be flexibly adjusted according to different coating conditions. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a thinning device applied to a transfer coater, which can be moved as a whole by moving the baffle, without disassembly and adjustment, and can be adjusted in thinning width by adding a gap adjustment assembly between the connecting bracket and the baffle, to adapt to various requirements.
